Thats the majority of alarm companies due to the number of false alarms. If you have a camera system that you can allow access in the event of an alarm police will arrive much faster.fwiw, I have a friend who's house was broken into several times about 5 years ago. She had an ADT alarm. The alarm worked fine. The perps simply didn't care, they knew a residential alarm had a certain amount of lag time built in (alarm co calling around before notifying the popo, then the popo not treating it as a high priority).
